As reported by the National Influenza Center - Pasteur Institute of Ho.
Ho Chi Minh, influenza surveillance system key southern countries found
cases of A/H3N2 flu originated from pigs.

This is a new 2-year-old female patients in Duoc, Long An influenza
have been treated at Children's Hospital 1 and then cured. Samples of
these patients have been tested in a laboratory at the CDC standard WHO
official - the United States and has been confirmed.

Yang said, this is the first case reported in Vietnam A/H3N2 flu
originated from pigs. This slight movement of cases and no evidence of
transmission from person to person.

The above translation
describe the first case (2F) of H3N2v in Vietnam (Duoc, Long An).
In contrast to earlier
reports, which described similar cases in the United States, this
report describes a PCR confirmed case in the Mekong Delta region in
southern Vietnam.

However, Hong Kong has
released 3 sets of sequences from Guangxi and Hong Kong (A/swine/Guangxi/NS2783/2010,
A/swine/Hong
Kong/2503/2011, A/swine/Hong
Kong/NS2439/2011) , which have similar H3 and N2 human genes
surrounding six internal genes from H1N1pdm09. In the United States,
all 12 of the H3N2v sequences in humans in 2011 have an H1N1pdm09 M
gene. Prior H3N2v
cases in the United States have PB1 E618D,
which is not in the swine isolates from Vietnam, but is in the new
sequences from Hong Kong and China, since E618D is in virtually all
H1N1pdm09 PB1 sequences.

The above report does not cite swine contact, so the origin of the
infection is far from clear. H3N2v in Vietnam is readily
distinguished from H3N2v in the United States.

Information on the
constellation of genes in the case in Vietnam would be useful.
